I notice that eclipse use a lot of memory (440MB).
The problem that most of them are physical memory and not virtual even i dont use eclipse (running GB dosnt help).

Any advice will be more than welcome.

Thank you

Unfortunately, ALL modern-day IDEs are memory eaters, and 440MB is on the low side. I was suffering until I upgraded my total system RAM from 1GB up to 2GB - although the email client app I run is also a memory hog.

Additionally, when you're debugging, there's the overhead for debugging and in the case of debugging webapps, the overhead for the webapp server that the debugged application is running in.

Eclipse should not be calling specifically for non-virtual memory, but it will run really slow if it doesn't have enough physical memory.

An IDE is no substitute for an Intelligent Developer.

How much memory Eclipse uses depends also on what plug-ins you are using in Eclipse.

I use Eclipse with the Java EE and WTP plug-ins everyday at work on Windows XP, and it rarely uses more than 200 MB memory.

I recommend 1GB with Eclipse if you are playing with multiple project in Java
